we have recently installed service pack 6 in weblogic application serever .
we started getting following errors in trace files ( indicated in alert log )
*** SESSION ID:(21.7570) 2004-05-07 10:52:52.484
FATAL ERROR IN TWO-TASK SERVER: error = 12592

Current SQL statement for this session:
SELECT A.GRP_ID GRP_ID, B.GRP_DEF GRP_DEF , B.CDNG_QUEST CDNG_QUEST, B.GRP_TYP_CD GRP_TYP_CD FROM USER_GRP_ACCESS A, GRP B WHERE A.VERSION_ID = :1 AND A.GRP_ID = B.GRP_ID AND A.USER_ID = :2 AND A.IS_TOP = 1 AND (nvl(B.CDNG_QUEST,'X')) != '0' AND substr(grp_def,1,1) <> '/' AND A.GRP_ID NOT IN (SELECT DISTINCT GRP_ID FROM USER_EXCLUDE_GRP WHERE VERSION_ID = :3 AND USER_ID = :4 ) ORDER BY CDNG_QUEST
but some screens were working fine ( this is happening intermittantly )
we conatacted weblogic support .
"User transaction rollback having problem in SP6" They suggested
1. Download latest and appropriate driver for Oracle 8.1.6 from Oracles web and put it in server's classpath before weblogic.jar (In this case remove classes12.zip from classpath which you are currently using now). Try this driver with SP6 and se eif you get same problems.
could you suggest how to install driver for oracle 8.1.6 from oracle.
Note : oracle database and application client connectivity was working fine with service pack 5 .
